which it does not recognize. The equipment sending this cause does not recognize the transit network either because q850 cause codes the transit network does not exist or because that particular transit network.

route to destination [Q.850] This cause indicates that the called party cannot be reached because the network through which the call has been routed does not serve the destination desired. This cause is supported on a network dependent basis. Cause No. 4 - send special information tone [Q.850] This cause indicates that the called party cannot be reached for reasons that ss7 cause codes are of a long term nature and that the special information tone should be returned to the calling party. Cause No. 5 - misdialed trunk prefix (national use) [Q.850] This cause indicates the erroneous inclusion of a trunk prefix in the called party number. This number is to sniped from the dialed number being sent to the network by the customer premises equipment. Cause No. 6 - channel unacceptable [Q.850] This cause indicates that the channel most recently identified is not acceptable to the sending entity for use in this call. Cause No. 7 - call awarded. being delivered in an established channel [Q.850] This cause indicates that the user has been awarded the incoming call and that the incoming call is being connected to a channel already established to that user for similar calls (e.g. packet-mode x.25 virtual calls). Cause No. 8 - preemption [Q.850] This cause indicates the call is being preempted. Cause No. 9 - preemption - circuit reserved for reuse [Q.850] This cause indicates that the call is being preempted and the circuit is reserved for reuse by the

from a syslog 3.4 How to decode cause codes from a SIP message 3.5 What if you don’t find the code 3.6 Q.931 ISDN Cause http://wiki.innovaphone.com/index.php?title=Reference:ISDN_Cause_Codes Codes 3.7 Display messages on IP2xx 4 Related Articles Summary H.323 (being based http://www.stat.ufl.edu/system/man/portmaster/trouble/cause.fm.html on Q.931 as ISDN is) uses the same cause codes as ISDN does. Such codes can be found in traces as well as in syslogs and call detail records Note that cause codes are coded differently in traces and syslogs. Here is how to extract cause codes from logs and traces and cause code how they are coded. Applies To All innovaphone H.323 products More Information How to decode cause codes from traces Within traces, you will find sequences similar to this: 0:0432:491:0 - TEI0.0 -> Q931.0: LL_RECV_RESULT data(13),FALC 08 02 80 02 45 08 02 82 81 1e 02 82 88 ....E........ if you have ticked the “trace” checkmark in the “interface configuration”. Additionally, you will see something isdn cause code like: 0:0432:491:3 - R_CALL.7 -> RELAY.0: SIG_DISC CAU = 82 81 if you have ticked the “trace” checkmark in the “protocol configuration”. In the example, the cause code thus is 82 81. The first byte (82) gives the Coding-standard and location. It is made up of: bit 8, 7, 6 and 5 usually 1000. Bit 4, 3, 2, 1 gives the location (that is, the entity generating the cause code). If bit 8 to 5 are unequal to 1000, the cause code is non-standard. The location is usually 0010, so that the second byte is usually 0x82 (10000010). The second byte (81) contains the cause code within the lower 7 bit (1). So you need to clear the MSB to look up the cause code in the table below, using the “Cause (hex)” column. You may also look it up directly using the “Cause, bit 8 set to 1 (hex)” column. There may be extraneous bytes giving further diagnostic information (Not described here and rarely used). In the example case, the cause code thus is 0x1, which says “Unallocated number”. How to decode cause codes from a CDR CDRs (call detail records) show caus
specifications. The cause is divided into three fields: The most significant bit (bit 8) is always coded as 1. The class (bits 5 through 7) indicates the general nature of the event. The value within the class (bits 1 through 4) indicates the event. Classes and values are coded as shown in Table A-1through Table A-7Some cause elements might also include an optional diagnostic octet. Table A-1 Class 000 and 001 (Normal Events) Cause Codes Bit 7 6 5 4 3 2 1 Hex Value Description 0 0 0 0 0 0 1 81 1 Unallocated (unassigned) number.
